The Geometry of Particle Physics: Garrett Lisi at TEDxMaui 2013

About the Presenter:
After getting his Ph.D. in physics from UC San Diego, Garrett moved to Maui, seeking an optimum balance between surfing and his theoretical research. While pursuing an unanswered question at the heart of Quantum Field Theory, he began to develop what he called "An Exceptionally Simple Theory of Everything," which proposed a unified field theory combining particle physics and Albert Einstein's theory of gravitation. His story and work have been featured at TED, in Outside Magazine, The New Yorker, Surfer, and recently in Scientific American.

About TEDx
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

The color 3D E8 orbit graphics I saw on "Wormhole" left me hungry to see more quantum art models of this. Outstanding and inspiring work.

Unlike strings, if this hypothesis fails, at least we have a beautiful mathematical shape as a consolation prize

3:35 We ARE accelerating downwards, AND we're prevented from moving further downwards by our chairs (and all of the other matter between us and the center of the earth). That matter is the "potential energy" being continually expended to maintain that matter's existence, and our stable presence resting on the surface.

So, what is accelerating us downward?

We are like fish in a stream, but being pressed against a grate or a screen, and wondering why we're not able swim upstream.

Well, Garrett misspoke slightly at about 2:40. The arrow doesn't "choose" a direction. If you balance it perfectly, and nothing disturbs it, it will just sit there. But something does disturb it. Something external to the arrow, and the arrow responds. It's not some magic thing - it's absolutely due to some tiny tiny bit of noise in the environment.

[marywright]

Love the way he presents the entire concept

[tomgroenland]

I consider myself fairly scientifically minded...but this was just whooosh

[skaterdude]

of the 30% I was able to follow- it was fascinating

[Shukster]

Does anyone know where i can buy this shirt?

[ctchump]

I would like to note that there are many new theories stating that no matter what we do, in terms of particle collision, we will never find a base molecule. This is based on new studies of the actual base geometry of particles themselves in relationship to their physics. Examples of this for one are shown in the nutrino effect. Although, this certainly is a very interesting piece, yet based on my studies at my university there is a strong pull in a new directions of physics. Surprise surprise.

I recall mention that Garrett's Lisi's e8 Lie Group possibly predicts some potential characteristics of the Higgs Boson as it did for other particles. Did the recent discovery at LHC match any of those predicted characteristics?

[roberthahn]

He legit lives in a van down by the river (snl) actually the ocean, saw him on through the wormhole, good dude.

[markus-sagen]

Wow! An actual Good and interesting TED talk

[laurentbenard]

''Complex geometry?'' He told us? No....😏😏😏
Just magnificent By our dear GARETT I'm just waiting for your THEORY OF QUANTIC GRAVITY!!!👍💪🌞🏄

[manjsher]

Never went anywhere, well now we know. Woo woo science.

[KipIngram]

I dispute that we seek to find out what the universe "is." What we seek is to understand how the universe behaves. We postulate models, our goal being the simplest possible model, that allow us to make correct predictions about future measurements. We actually have no idea whether these things truly exist or not. We don't see them. We don't feel or smell them. We see an indicator on some instrument wiggle, and that wiggle confirms or contradicts our prediction.

Without space and time, it wouldn't be a 4-dimensional fabric, it would be a non-dimensional pre-fabric

[your.own.universe-tube]

I released little to no real details on the subject as I have my own papers I wish to publish in the next few years but, I did release the most noticeable geometric shape that is particle physics. Everyone is definitely going to want to go watch. Today's time, to get my name out there, I'm going to use the internet the way I feel it was intended for. This is how you quickly reach masses of people. When the time comes to release my papers, in defense to not sound crazy, I released the visual picture of my research, and my theories. Everyone should check it out.

[curttom]

Hi could someone give me the name of the picture of the Higgs particle at 1:28 seconds into the video I would love to get a copy. Thanks!!

"Turns out they take forever to inflate... lmao... gotta love hyperbola

[jennybardoville]

I thought it very honest of him to keep saying 'we think'. Too often, we forget that what is presented by science is essentially mid-experiment. In addition, what he is presenting is of a physical experiment and until scientists factor in consciousness and it's creative power for producing the results sought, literally creating what is believed to be true, no result will be final. We're already popping into and out of existence particles every so many trillionth seconds. Building bigger machines cannot prove anything except big budgets. What we are looking for is what we are looking with.
